IMPROVEMENT IN PROPULSION OF VESSELS.

Specification forming part of Letters Patent No. 182,517, datedSeptember 26, 1876; application filed March 1, 1876.

' ment in Propellers and I hereby declare the following to be a full,clear, and exact description of the construction and operation of thesame, reference being bad to the annexed drawings, making a part of thisspecification,

and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a side view of a vesselhaving my propeller applied; and Fig. 2 is a horizontal sectional viewthereof, Fig. 3 is a perspective View of one of my propellers.

The nature of my invention consists in the construction and arrangementof a device for propelling vessels or other bodies through water, aswill be hereinafter more fully set forth in the annexed drawings.

A on the drawings designates the hull or shell of any vessel or otherbody to be propelled through the water. On each side of the shell A, ata suitable distance from the front end, is secured a case, B, made inwedge form, closed at top and bottom and open at the rear side, saidrear side being the wide or base end of the wedge, while the narrow orfront end is closed and close to the side of the shell, the casecorresponding on its inner side with the curvature or shape of the shellA. At the narrow front end of each case B is hinged or pivoted a wing,O, which extends the entire length of the case. a is a bolt or rod thatpivots the wings. From said rod an arm, 12, extends into the shell A,the inner ends of said two arms b I) being connected with and operatedby a suitable engine so as to cause the wings O O to vibrate, laterallyfrom side to side in the cases B B. This vibration of the wingscompresses the water first against one side of the case, and thenagainst the other, and the resistance of the water to compression causesthe vessel or body A to be propelled forward.

This invention is applicable'to any vessel or other body that it isdesired to propel through water, and very great speed may be attainedthereby.

[t is obvious that the principle of this invention, namely, thepropulsion of bodies through water by the means hereinbefore described,may be applied in a similar way to the propulsion of bodies throughother medium, such as the air.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A laterally-vibrating wing pivoted within a wedge-shaped caseattached to a vessel or other body to be propelled, substantially asherein set forth.

2. The combination, of the hull or shell A, wedge-shaped cases B B,wings O O pivoted therein, pivot-rods a a, and the arms I) b 0011-nected to and operated by an engine, all substantially as and for thepurposes herein set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
